Feasibility Study on Anomalous Small-Angle X-ray Scattering near Sulphur K-edge

Anomalous small-angle X-ray scattering (ASAXS) is expected to be a powerful and vital tool for the structural study of soft matter. We investigated feasibility of ASAXS near sulphur K absorption edge at SPring-8. Scattering pattern was successfully obtained and the dependence of scattering intensity on the energy of X-ray well agreed with the calculated one. This study can be the basis of structural study of soft matter using ASAXS, especially non-crystalline/amorphous materials.
